Period cycle: When should you exercise for best results?

Knowing the right time on your menstrual cycle to exercise could improve your fitness.

A new study has shed some light on when is best to workout during the menstrual cycle, suggesting that training during the first two weeks could be most beneficial for muscles.

How the menstrual cycle affects sports training is largely unexplored, but came under the spotlight recently when during the Rio 2016 Olympics, Chinese swimmer Fu Yuanhui admitted feeling tired during her performance due to starting her period the day previously.
